Yes, Frederick (see his comment below) is absolutely right. The man on the right of Hitler is Arno Breker, Hitler’s favourite sculptor, who accompanied Speer and the Fuehrer on their lightening, three hour early morning tour of Paris, 70 years ago this month.
Hitler wanted these ‘artists’ to accompany him so that they could see the glories of Paris, and thus be sure to construct bigger glories back in the German capital in response. And Hitler’s words to Speer that same evening (which Speer recorded in his autobiography ‘Inside the Third Reich’) give a chilling insight into the mentality of the German leader. ‘In the past I often considered whether we would not have to destroy Paris,’ said Hitler, ‘but when we are finished in Berlin, Paris will only be a shadow. So why should we destroy it?’
As Speer said, the idea that Hitler had considered destroying Paris merely because he didn’t want the French capital to overshadow Berlin reveals that he was most certainly a ‘ruthless and mankind-hating nihilist’.
A realisation that didn’t stop Speer serving him subsequently as armaments minister though, did it?
